The deeper question

Teteles’ structures may encode solar knowledge, but their alignment alone cannot reveal exactly how ancient people used them.

The deeper issue is not whether ancient people watched the sky; Mesoamerican evidence shows that they did. It is whether Teteles’ alignments demonstrate a dedicated observatory rather than ceremonial architecture that also marked seasonal solar positions. Archaeoastronomical research warns that alignment alone cannot establish builders’ intentions, while debates over famous equinox effects show how easily later interpretations can overstate precision.

• Archaeoastronomical methodology cautions that astronomical alignments do not by themselves prove a site’s importance, purpose, or meaning to its builders.doi
• Research on Mesoamerican pyramids has shown that apparent equinox effects may not identify a precise intended date or purpose.hgrupoeditorial
• Other Mesoamerican sites demonstrate longstanding astronomical observation, making solar knowledge plausible without proving that Teteles was a dedicated observatory.spaceinframes +2
